Shock Absorber Preload Analysis using CATIA Generative Structural Analysis (FEA)

William Harbin

2 0 Expert
This BND TechSource video shows how to use CATIA Generative Structural Analysis (FEA) to prove the following: 1) The spring rate will be linear when the spring has a consistent (evenly spaced) pitch and a constant diameter. 2) Preloading the spring on the coil over assembly will NOT change the rate of the spring. 3) Preloading the spring on the coil over assembly WILL affect the deflection at load (length at load) of the shock absorber.

This BND TechSource video shows the steps for creating a “template” part for our Transverse Module Involute Helical Gear. This part may be modified by simply changing the parameters of any/all of the following five formulae: Fw - Face width // length parameter [Fw = input] z - number of teeth // real parameter [z = input] Tpa - Transverse Pressure Angle // angle parameter [Tpa = input] m - module // length parameter [m = input] Ca - Cylinder helix angle // angle parameter [Ca = input] Next we will look at using CATIA V5 to create the Normal Module Involute Helical Gear.

PETAL CREATION PROCESS: There are two main methods for modeling the petals as follows: 1. Surface modeling method: draw a 2D surface of suitable shape using the Create > Line tool and a volume to the surface using the Shell modifier. Edge softening is achieved with MeshSmooth modifier. 2. Using Symmetry Modifier: if we are aiming for absolute symmetry of the two halves of the petal, we must use the Symmetry, but this step must precede MeshSmooth. 3. Solid modeling method: place a standard Plane primitive in the workspace (Perspective Viewport). The desired shape is obtained by selecting and moving vertices. The remaining steps of shaping the desired form are analogous to those of the method described at the beginning of the tutorial. 4. Clone the petals: using Pivot > Affect Pivot Only, where by default the pivot point is at the center of the base of the object. In this case, a total of five rows of four petals are modeled. They mus be grouped by Group so that they do not move during further work.

Animating the model: it is performed by creating keyframes in the track under the working space that can be adjusted, changed and deleted. 2. Animating a camera: it is analogously to step 1. 3. Rendering process: it is required to be completed before saving the final image or animation in a desired format.

This BND TechSource video shows how to create a “template” part for an Involute Spur Gear. This part may be modified by simply changing the parameters of any/all of the following three formulae: z - number of teeth // real parameter [z = input] Rpa - Ref Pressure Angle // angle parameter [Rpa = input] m - module // length parameter [m = input] And the Undercutting issue can be resolved by introducing Profile Shift which affects the Center Distance between gears as well as adjusting the Addendum and Dedendum circles.

Their advantage is that they move in all directions, and most often this happens with changes in the center of gravity. Some models use a system of counterweights, which helps to stay still on slopes with an inclination of 33° (Pico Rover). Some are used to study the environment, others - on the lunar surface. They are usually equipped with a high-resolution camera. The robot is tentatively named by the author VESPER-006 ("Vesper" means Venus) due to the fact that the planet Venus is a "double" of the Earth due to the close dimensions, although the surfaces of the two planets are completely different. The spherical shape was purposefully chosen to make the robot to resemble the planet it was inspired by. VESPER-006 is thought to be with an innovative design and drive method. It is suitable for research and analysis of the environment regardless of what it is (air, liquid or field). The temperature range is also wide (between -40 and +120°C). The mechanism must be able to reach the point with coordinates (x, y, z) in time space [t]. The design is stylish, simple and facilitates the rotation of the robot around its axis, as well as its movement in space. The dimensions must be such that they can take the weight of the engine and equipment. Apart from an aesthetic purpose, to make the design more interesting, the three side elements (Stands) have been added for their practical function - to stabilize the robot when it is in a static position. The main steps in the modeling process are as follows: 1. Modeling the side element: first a curve with the desired shape is drawn using Create > Shapes > Line. After that it is extruded by Modifier Panel > Extrude tool. To edit the object, right-click on it and select Convert to Editable Poly. The model can be modified by selecting individual polygons, edges or vertices and using the Extrude and Bevel tools. 2. Clone the side element: by right-clicking on it and selecting Clone. 3. Modeling the spherical body: the outer Geosphere is transformed into a grid by selecting all polygons, Inset and Extrude. The selected polygons should be removed.

Open Material Editor (hotkey "M"): the main settings of the material (ambient, diffuse, glossiness and specular level) are shown in Step 1. 2. Coloring the inner sphere: it should contrast to bring out the golden material of the outer grid. An example is given in Step 2. 3. Adding lights and shadows: this is one of the most complex stages of modeling in 3DS Max, usually done right before animating the model. It should be noted that lights can also be animated. They are selected from the main menu Create > Light. The favorite light of the author is Omni. Each of the lights can be adjusted appropriately to produce realistic shadows and highlights.
